Hydraulically applied mulches are an excellent form of erosion control, especially in revegetation applications. The term “hydromulching” is known in the construction industry as an installation technique where an engineered mulch is mixed with water, seed, fertilizer and other amendments, which is then sprayed from a pressurized nozzle onto the ground. Coating the ground with a thin layer of hydromulch not only protects the soil and seed from erosion while the seed germinates, but also serves as a moisture bed to expedite the germination process.
Hydraulically applied mulches save a lot of time and labor during installation, serving as a great alternative to sod for erosion control, steep hill slopes, and commercial and residential landscaping. When the hydromulch layer cures atop your subgrade, it creates a crust that wicks stormwater over top the area. This keeps seed and soil from washing out during storm events before the vegetation is established. When mixed with seed and fertilizer, Hydraulically Applied Mulch forms a homogeneous slurry that ensures an evenly distributed stand of grass.
